Add a PYACTION version of UDQ_M3

[lisajulia]

This does not fully work yet though, as FU_VAR54 is wrong from report step 4 on

Compare with:

"YOUR_PATH/opm-simulators/tests/run-comparison.sh" \
    "-i" "YOUR_PATH/opm-tests/udq_pyaction" \
    "-j" "YOUR_PATH/opm-tests/udq_actionx" \
    "-f" "UDQ_M3_PYACTION" \
    "-g" "UDQ_M3" \
    "-r" "YOUR_PATH/opm-simulators/build-cmake/tests/results/flow+pyaction_udq_m3" \
    "-b" "YOUR_PATH/opm-simulators/build-cmake/bin" \
    "-a" "1e+5" "-t" "2e-5" \
    "-c" "YOUR_PATH/opm-common/build-cmake/bin/compareECL" \
    "-y" "BOTH" \
    "-e" "flow" "--"

@blattms: Maybe next week, we can have a look together at this?
